AI Article Synopsis

  • - The study focuses on a patient who had an above-the-knee amputation, noting that the residual bone length decreased over time after the surgery.
  • - The patient had previously received a total hip replacement, and X-rays showed that the cement from the hip surgery started to protrude due to bone loss one year post-amputation.
  • - While previous research highlighted changes in the bone structure of amputation stumps, this case is unique as it documents significant changes in the actual length of the residual bone.

Article Abstract

Several studies have investigated the anatomical adaptations in amputation stumps. In this study, we present a case report of a patient who underwent an above-the-knee amputation and, over the course of time, the length of the residual bone spontaneously shortened. The patient had undergone a total hip replacement in the same leg, and the cement mantle of the hip replacement, which could be seen within the medullary canal in the early postoperative X-rays, protruded due to bone resorption one year after the amputation Although changes in bone microarchitecture in amputation stumps are well established, this is the first report of macroscopic changes in its actual length.
